United Nations Secretariat Building

The United Nations Secretariat Building is a 154 m (505 ft) tall skyscraper and the centerpiece of the United Nations Headquarters, located in the Turtle Bay area of Manhattan, in New York City. The lot where the building stands is considered United Nations territory, although remains part of the United States.


It has 39 stories and was completed in 1952. The building was designed by the Brazilian architect Oscar Niemeyer and the French Le Corbusier. This building is connected to the Conference Building to the north that houses the General Assembly, the Security Council, among others, and a library building to the south (see foreground of the photo).

The building houses the administerial functions of the UN, including day-to-day duties such as finance and translation, and the offices of ambassadors and delegates.

As part of the UN complex, the building is designated as being located in international territory, subject to an agreement between the United Nations and its host country, the United States.

On December 21, 2010 The UN Building was evacuated due to a sewer backup in the building. The UN is currently being renovated.
